Acalculia and Dyscalculia

Even though it is generally recognized that calculation ability represents a most important type of cognition, there is a significant paucity in the study of acalculia. In this paper the historical evolution of calculation abilities in humankind and the appearance of numerical concepts in child development are reviewed. Developmental calculation disturbances (developmental dyscalculia) are analyzed. It is proposed that calculation ability represents a multifactor skill, including verbal, spatial, memory, body knowledge, and executive function abilities. A general distinction between primary and secondary acalculias is presented, and different types of acquired calculation disturbances are analyzed. The association between acalculia and aphasia, apraxia and dementia is further considered, and special mention to the so-called Gerstmann syndrome is made. A model for the neuropsychological assessment of numerical abilities is proposed, and some general guidelines for the rehabilitation of calculation disturbances are presented.     

Does quantity generate quality? Testing the fundamental principle of brainstorming

The purpose of this work is to test the chief principle of brainstorming, formulated as "quantity generates quality." The study is included within a broad program whose goal is to detect the strong and weak points of creative techniques. In a sample of 69 groups, containing between 3 and 8 members, the concurrence of two commonly accepted criteria was established as a quality rule: originality and utility or value. The results fully support the quantity-quality relation (r = .893): the more ideas produced to solve a problem, the better quality of the ideas. The importance of this finding, which supports Osborn's theory, is discussed, and the use of brainstorming is recommended to solve the many open problems faced by our society.     

Autobiographical recall training in elderly adults with subjective memory complaint: a pilot study

Subjective memory complaint is a self-reported memory impairment which affects elderly people. This problem does not interfere with daily living activities but could decrease quality of life. This study's purpose was to verify whether a specific, newly developed, autobiographical recall training could modify self-perception of memory of subjects with subjective memory complaint. Seven elderly subjects (4 women and 3 men; mean age 65.5 yr., SD=11) with such complaint, evidenced through a specific questionnaire, attended the training course and were prospectively assessed on standard neuropsychological tests, depressive symptomatology, and self-perception of memory. Self-perception of memory, as assessed by scores on a formalized questionnaire, improved significantly after the training, while depressive symptoms did not change. Neuropsychological performances were normal before and after the training, but a statistically significant improvement was observed only on the phonological fluency test. Thus the present pilot study suggested that the training may be effective in improving self-perception of memory and metamnestic capacity in elderly people with subjective memory complaints but not in changing subjects' depressive symptoms. This requires replication of this work with a much larger sample so statistical power is adequate.     

A bottom-up view of toddler word learning

A head camera was used to examine the visual correlates of object name learning by toddlers as they played with novel objects and as the parent spontaneously named those objects. The toddlers’ learning of the object names was tested after play, and the visual properties of the head camera images during naming events associated with learned and unlearned object names were analyzed. Naming events associated with learning had a clear visual signature, one in which the visual information itself was clean and visual competition among objects was minimized. Moreover, for learned object names, the visual advantage of the named target over competitors was sustained, both before and after the heard name. The findings are discussed in terms of the visual and cognitive processes that may depend on clean sensory input for learning and also on the sensory–motor, cognitive, and social processes that may create these optimal visual moments for learning.     

The Social Context of Organized Nonbelief: County‐Level Predictors of Nonbeliever Organizations in the United States

Many recent social scientific studies have noted that the percentage of Americans with no religious affiliation is on the rise, but few have examined the nonbeliever organizations that some of these “nones” might join. This study uses an original data set, the first attempt at documenting the population of local nonbeliever organizations in the United States, to explore where these groups are more likely to flourish. Though one might assume that less religious counties, as measured by the percentage of those with no stated religious affiliation, would be more likely to contain nonbeliever organizations, this article provides evidence that they emerge more frequently and in greater numbers in counties with proportionally more evangelical Protestants. The percentage of evangelicals among a county's population is strongly associated with both the existence (dichotomously coded) and the number of nonbeliever organizations, even when controlling for a range of demographic and institutional factors.     

Self‐Regulatory Growth Effects for Young Children Participating in a Combined Social and Emotional Learning and Mindfulness‐Based Intervention

The authors analyzed findings from a counselor‐delivered social and emotional learning and mindfulness‐based intervention with twenty‐three 3‐ and 4‐year‐olds from economically disadvantaged backgrounds. Using a multilevel modeling approach to illustrate students' growth across multiple behavioral observations in a randomized controlled design, the authors found that the treatment group exhibited more self‐regulatory‐related behaviors on days when the intervention occurred. Qualitative analyses revealed that the students adopted kindness language consistent with the intervention. Implications for practice are suggested.     

The daily spillover and crossover of emotional labor: Faking emotions at work and at home

This diary study among 75 Spanish dual earner couples investigates whether emotional labor performed by employees at work has implications for themselves and for their partner at home. On the basis of the Spillover-Crossover model, we hypothesized that individuals' surface acting at work would spill over to the home domain, and that surface acting at home, in turn, would reduce individuals' levels of well-being. Moreover, we predicted crossover of experiences lived at home between the members of the couple. Participants filled in a diary booklet during five consecutive working days (N = 150 participants and N = 750 occasions). The results of multilevel analyses show that daily surface acting at work has an indirect relationship with daily well-being through daily surface acting at home. In addition, we found a bi-directional crossover of surface acting at home and well-being between both members of the couple. These findings indicate that emotional labor has implications not only for employees themselves, but also for their partner at home – on a daily basis.     

The emergence of positive occupational health psychology

The aim of this paper is to provide an overview of the emerging concept of Positive Occupational Health Psychology (POHP). We discuss the usefulness of focusing on positive constructs in order to understand the path to health and well-being at work. We describe research findings on several POHP topics, including engagement, psychological capital, and job crafting. Additionally, we review the first positive interventions in this field and conclude by identifying some specific questions for future research.     

Expectativas de probabilidad teórica y de frecuencia empírica en juegos de azar

Resumen

La investigación explora la capacidad de tres escolares, de ocho a once años, para efectuar estimaciones de probabilidad de eventos aleatorios, y la conducta suya de predecir los resultados reales en estos mismos eventos, a lo largo de una secuencia de 21 experiencias, repetidas cada una tres veces. Se comparan de manera sistemática las estimaciones estadísticas subjetivas, la probabilidad estadística objetiva, la predicción empírica de los sujetos y los resultados reales de eventos aleatorios en ocasiones anteriores. El niño más pequeño realizó sus predicciones sobre la base de los resultados reales anteriores más que sobre la base de sus propias estimaciones de la probabilidad, mientras los dos mayores las realizaron por igual sobre una y otra base.
